REUBEN o. sTUTsMAN, OF vDas MOINES, IOWA.

PEANUT-Rons'rnn.

To all whom it may concern:

Be it known that I, REUBEN O. STUTSMAN, a citizen of the United States,residing at Des Moines, county of Polk, and State of Iowa, have inventeda certain new and use ful Peanut-Roaster, of which the following is aspecification.

This invention relates to that class of peanut roasters in which aroasting cylinder is turned by means of spring actuated mechanism, andthe same spring actuated mechanism is arranged to operate a centrifugalball governor for the purpose of drawing attention to the peanutroaster, and in which the roasting cylinder is heated by means ofgasolene burners, and in which steam is generated for the purpose ofwarming peanuts and for the purpose of operating a steam whistle. y

My object is to provide a peanut roaster of this class, of simple,durable and inexpensive construction, in which the roasting cylinder iselevated to position over the warming pan and its contents dumped whenthe hinged cover of the peanut roaster is elevate A further object is toprovide improved gearing devices for operating the roasting cylinder andthe ball governor and also in this connection to provide means forautomatically locking the shaft to which the driving spring is attachedagainst backward movement.

A further object is to provide improved means for heating the water inthe warming pan and for producing steam, which means are so arranged asto be heated by the same burners that serve to roast the peanuts in theroasting cylinder.

My invention consists in the construction, arrangement and combinationof the various parts of the device, whereby the objects contemplated areattained, as hereinafter more fully set forth, pointed out in my claims,and illustrated in the accompanying drawings, in which- Figure 1 shows aside elevation of a peanut roaster embodying my invention with theroasting cylinder in position for discharging its contents. Fig. 2 showsa detail sectional view illustrating a part of the warming pan with thesteam whistle and water pet-cock in position. Fig. 3 shows a centrallongitudinal sectional view through the peanut roaster with theroastingcylinder in position for roasting peanuts. Fig. 4

shows a top or plan view of a part of the device with the cover of thepeanut roaster removed to illustrate the gearing mechanism for operatingthe roasting cylinder and other parts and the heating device. F ig. 5shows a detail view of one side of the machine illustrating the ballgovernor device, and Fig. 6 shows an enlarged detail view illustratingthe means for automatically locking the shaft to which the spring isattached against backward movement.

Referring to the accompanying drawings, I have used the referencenumeral 10 to indicate the frame of the peanut roaster mounted on thesupporting wheels 11. On one end of the frame is a shaft 12 extendedacross the machine and-having bearings in the sides of the frame. Thisshaft has a convolute spring 13 xed on one end, the other end of. saidspring being fixed to a casing 14 rotatably mounted on the shaft 12 andhaving cog teeth 15 on its periphery. I provide for winding up thespring as follows: The numeral 16 indicates a shaft having bearings' inthe sides of the machine frame and having a detachable crank 17 on oneend. On the other end is a small pinion 18 in mesh with a large pinion19 fixed to the shaft 12. Mounted in the frame above the casing 14 is ashort shaft 20 having a small pinion 21 thereon in mesh with the cogteeth 15 on the spring casing 14. On the same shaft 2O is a pinion 22for purposes hereinafter made clear.

I have provided for automatically locking the shaft to which the springis attached against backward movement as follows: Mounted on the shaft16 is a pivoted arm 23 extended toward and over the pinion 19, as shownin Fig. 6. The arm 23 is rotatably mounted upon the shaft 16 and it isengaged at one side by an eXtensible coil spring 24 on the shaft 16,which spring is engaged at its other end by a collar 25 fixed to theshaft 16. In this way, the spring serves to apply friction to the arm 23in sufiicient amount to cause the arm 23 to move with the shaft 16 solong as said movevment is not interfered with by a stationary object.Mounted upon the arm 23 is a pinion 26 in mesh with the pinion 18 andalso designed to mesh with the pinion 19 when the arm 23 is at itsdownward limit. The pin 27 is fixed to the frame in position to beengaged by the end of the arm 23 to thereby limit the upward movement ofsaid arm as tion applied to the arm 23 by the spring 24 will besufficient to carry the arm 23 upwardly to the position shown by dottedlines in Fig. 6. Then the pinions 18 and 26 may freely rotate and thepinion 18 wil drive the pinion 19 and in this manner wind up the spring13.l When the operator releases the crank 17, the spring 13 will causethe pinion 19 to move in a reverse direction and this will operate thepinion 18 and the shaft 16 in the reverse direction thereby immediatelycausing the arm 23 and its pinion 26 tol move downwardly into engagementwith the pinion 19, as shown by solid lines in Fig.4 6. This will alwaysoperate to immediately stop the pinion 19 and'firmly lock it againstfurther rotation for the reason that the pinion 26 and the pinion 19,bot-h being in mesh with thel pinion 18, will have their Aadjacentportions moved in opposite directions by the pinion 18, and, therefore,even if only the ends of the teeth of the pinions 19 and 26 touch eachother, the pinion 19 will be firmly locked and if the ends of the teethshould slip past each other,

then the teeth themselves will engage each other in suoli a manner as toprevent further movement of the pinion 19. Y

One of the particular advantages of this device is that as soon as thecrank 17 is operated to wind up the main spring, the pinion 26 isimmediately elevated out of engagement with the pinion 19 and thenduring the time that the crank 17 is being rotated, the pinion 26 isheld out of engagement with the pinion 19, and, hence, there is no noiseor friction such as is the case with an ordinary spring actuated pawlfor preventing backward movement of the pinion 19.

Vhen the pinions 18, 19, and 26 are inv the` position shown in Fig. 6,it is obvious that the pinion 19 is locked against rotation in eitherdirection.

necessary to the operation of the locking mechanism for the reason thatwhen power is applied to the shaft 16 to turn the pinion ends by whichit may be elevated.

The roasting cylinder is indicated by the `numeral 31 and is providedwith a dooi" Furthermore, the fric`v tion device comprising the spring24 is not oieninfr at one side covered b Y a hinged Vdoor rlhe ends ofthe roast-ing cylinder are provided with'j'ournals extended outwardlybeyond the cylinder and on one of said oui-nais is a pinion 34 designedto mesh with the pinion 22 on the shaft 2O when the roasting cylinder isin its position for roast iiig. l support the roasting cylinder asfoilows: Pivoted to the sides of the frainelO -aie two bell crank levers35 each having one end slotted to receive a journal 33 and each having:it its other end, a link 36 having a limited sliding connection withthe bell crank lever 35; and the other end of each link 36 is pivoted tothe hinged cover 28, as 'clearly shown in Fig. 1. rFhis part of thedevice operates as follows: Vv'hen the roasting cylinder is in theposition shown in Fig. 3, it will be rotated by the pinion 22. when theoperator grasps the handles 3() to raise the cover 28, the arms 36 andthe bell crank levers 35 will elevate the roasting cyl- -inder and moveit to the position shown in Fig. 1, where it will be directly over thewarming pan. rifhe contents of the cylindei' may then be discharged intothe warmingl pan by opening the door 82; or the roasting cylinder may beremoved from the bell crank levers by grasping the ends of the journals33 and moving them out of the slotted ends of the bell crank levers.When the ioasting cylinder is in the position shown in Fig. 3, theprojecting ends of the journals 83 are designed to rest in engagementwith the antifric'tion rollers 37 iiXed to thefi'ame 10, so that thecylinder may freely rotate with a minimum of friction.

TheV warming pan is formed with double walls 88 and 39 to provide awater and steam chamber between them. In the bottom of the warming panis a pet-cock 4() and arranged at one side of the warming pan at aboutthe water level thereof is a second petcock 41 by means of which theoperator may determine the quantity of water in the warm# ing pan.Communicating with the top portion of the warming pan `is a pipe 42having a steam whistle 43 connected with it and a discharge pipe 44. lprovide for heating the water in the warming pan as follows: Thereference numeral indicates series of gasolene burners of ordinaryconstruction communicating with gasolene feed pipe 46, said burnersbeing all arrangedV under the roasting cylinder so that the heat fromthem lis applied to the roasting cylinder. Arranged above tlie gasoleneburners 45 is a water pipe 47 having av pipe 48 communicating with it atone end, which pipe discharges into the warming pan between the upperand lower walls thereof, as shown in Fig. 8,' and at the `other end ofthe pipe 47 pipe 49 communicating with the bottoni of the warming pan.Said pipe 47 is so arranged that it will be heated by the same burnersthat are rhen, Y

los

used to heat the roasting cylinder, and, j hence, no additional burnersare required for keeping the water in the warming pan heated and forproducing steam required to 0perate the whistle.

The means for operating the ball governor device comprises a shaft 50extended across the machine frame and having a small pinion 5l on oneend in mesh with the cog teeth l5 of the spring case la. On the otherIend of this shaft is a large pinion 52. Above the pinion 52 is a shortshaft 53 having a small pinion 5e thereon in mesh with the pinion 52 anda large worm-wheel This wormwheel 55 is in mesh with a worm 56 arrangedon the ball governor shaft of ordinary construction, the ball governorbeing indicated by the reference numeral 57. ln this way I obtain powerfor ruiming the ball governor direct from the cogs l5, and, hence, theshaft 50 and the mechanism connected with it for operating the ballgovernor need only be comparatively light and inexpensive. 'Heretoforedevices of this kind have had the ball governor device connected withand operated by the gearing mechanism that was used to rotate theroasting cylinder, and, hence, it had to be strong and heavy enough totransmit the power required for operating the roasting cylinder, but bythe arrangement shown, there are no strains thrown upon the ballgovernor mechanism except such as are required to keep the ball governoritself in motion. In this way, I not` only provide an inexpensiveconstruction, but I eliminate a great amout of friction.

lt is obvious that the device herein shown and described is especiallyadapted for use in roasting peanuts, but that it could be used forroasting other articles or for other purposes without departing from thespirit of my invention.
